I've been thinking about this a lot recently, and I actually miss it. Yes, it was ugly, but it gave people agency. Facebook forces every single person to "look" more or less the same. I imagine there has to be at least one kid who got into CSS styling by trying to make their MySpace profile look cool, introducing them to web design...

Facebook's enforced "look" is sort of the equivalent of a school uniform, except for everyone, and it's stifling.
